"The future period will be tough, and possibly more difficult than during the first nine months of pandemic of the new coronavirus. Creation of the new vaccine does not mean the end of pandemic", the official said.
He reiterated that as the winter comes, it does not affect the increasing number of infections. Only behaviour of people changes; they spend more time in closed spaces than they do in summer. And that improves the rate of the spread of infection.
Al-Mandari added that none of the four currently developed and tested vaccines have been approved yet.
"The vaccine will not be approved until its complete safety for people is provided. We heard about four vaccines that are considered safe, but repeated tests and researches should be performed. So no country or company have got the official permission for massive production of vaccines", the official said.
According to Worldometers, 57 million cases have been observed since the pandemic began; over 1,000,000 deaths were confirmed.
